Execute the below query without the double quotes

"select * from table_name
--This is a comment line"

The above query will result in an "IndexOutOfRange" exception. I debugged the source code and found that the problem is because, in the RemoveComments() function, there is code as follows

else if ((source[i] == '-' && (i < length - 1) && source[i + 1] == '-'))
{
i++;
while (source[i] != '\n')// exeception will occur at this line
{
i++;
}
i--;
}

the while codition is only checking for '\n', but in the above query since the comment is in the last line, it will never find another '\n', so the loop index will grow to a value greater than the length of string causing the above exception

The while loop should actually be modified as follows
while( i < length && source[i] != '\n' )
{
i++;
}
